| New non-invasive method can detect Alzheimer's disease early Posted: 22 Dec 2014 11:30 AM PST A noninvasive MRI approach that can detect the Alzheimer's disease in a living animal, well before typical Alzheimer's symptoms appear, has been developed by researchers. The research team created an MRI probe that pairs a magnetic nanostructure with an antibody that seeks out the amyloid beta brain toxins responsible for onset of the disease. The accumulated toxins, because of the associated magnetic nanostructures, show up as dark areas in MRI scans of the brain. |
| Universality of charge order in cuprate superconductors Posted: 22 Dec 2014 10:15 AM PST Scientists have now identified charge order in HgBa2CuO4 , a pristine cuprate material. A further important result of the study is the finding that the charge order is closely related to quantum oscillations under a magnetic field. Finding a universal connection between the period of these quantum oscillations and the spatial period of the charge order is one of the achievements of the study. |
| Posted: 22 Dec 2014 10:13 AM PST Researchers have opened the door to low-power off/on switches in micro-electro-mechanical systems, MEMS, and nanoelectronic devices, as well as ultrasensitive bio-sensors, with the first observation of piezoelectricity in a free standing two-dimensional semiconductor. |
| New technology makes tissues, someday maybe organs Posted: 22 Dec 2014 08:16 AM PST A new device for building large tissues from living components of three-dimensional microtissues borrows on ideas from electronics manufacturing. The Bio-Pick, Place, and Perfuse is a step toward someday making whole organs. |
